Legalize based on lethality and addictiveness. Use the Dutch model, change it based on cultural expectations and national circumstances. First use test zones like towns or counties. Measure changes in criminal, medical, and public perspective, happiness, and strength/stability over a period of time. Adjust as necessary. Put measures into place for proper balance of freedom and control. Cautiously apply countrywide. Repeat as necessary.

I like this.

I'd go so far as to even suggest modifying existing drugs so that the dosage is far more mild and safe for recreational use. Not saying we should do this for heroin, but there are other opiates quite similar like morphine or oxy that come with serious side effects, yet are legal in a limited form. I think that limitation is key. If we can change the lethality and addictiveness, but still sell a drug that gives a bit of that wanted feeling without nearly as much risk of overdose/addiction, people'd probably go for it.
